Two things I noticed: when you have multiple Flash Video conversions to choose from (e.g. http://www.archive.org/details.php?identifier=vivaldi_rock&amp;newflash=1) then the ">" indicating which version is being played remains in the top position (first video) even when another one is being played... (Firefox 2, OS X 10.3.9)

Also the progress bar seems missing.

Full screen looks quite good, now only if there was a way to optimise uninterrupted playback for higher encoded Flash Videos...? But it's hard to tell from here where the bottleneck is, it could also well be my rather slow wireless internet connection...

Maybe a "double size" mode would also be good to have at some point for videos that don't look too good in full-screen mode...?
